Scenario 1:
- A team and its corresponding SharePoint team site are processed as different objects by the same backup job. This scenario also applies to an entire organization backup.
- Either a team or a corresponding team site is then removed from processing.
- A team and its corresponding SharePoint team site are processed as different objects by different backup jobs targeted to the same object storage repository.
- Either a team or a corresponding team site is then removed from the corresponding job.
- A team object has been backed up for a certain period. After which, a corresponding team site has been added to the same backup job.
Backup
- Under certain conditions, the backup of group mailboxes may hang with no data processed although proxy threads are allocated. Full resolution may require certain proxy config changes, contact Veeam Support for assistance.
